Retested salt to verify ppm @3400 and recalibrated my PoolPilot. Everything is perfect now. Sean, reading all of your previous posts regarding the PoolPilot and the advice you have given me reassures me that I definitly made the right purchase. Thanks to you and all the others who have helped me. I have a firm grasp on water chemistry and I also have a sparkling crystal clear pool!
